Corvin Castle, also known as Hunyadi Castle or Hunedoara Castle (Romanian: Castelul Huniazilor or Castelul Corvinilor; Hungarian: Vajdahunyadi vár), is a Gothic-Renaissance castle in Hunedoara, Romania. It is one of the largest castles in Europe and figures in a top of seven wonders of Romania.
Corvin Castle was laid out in 1446, when construction began at the orders of John Hunyadi (Hungarian: Hunyadi János, Romanian: Iancu or Ioan de Hunedoara) who wanted to transform the former keep built by Charles I of Hungary. The castle was originally given to John Hunyadi’s father, Voyk (Vajk), by Sigismund, king of Hungary, as severance in 1409.[2] It was also in 1446 when John Hunyadi was elected as the regent-governor of the Kingdom of Hungary by the Diet.
